Title: Manufacture of condensation products from urea, thiourea, or their derivatives and an alcohol or a ketone
IPC: C08G12/02
Filed: 1927-10-04
Abstract: 278,390. I. G. Farbenindustrie Akt.- Ges. Oct. 4, 1926, [Convention date]. Plastic compositions containing cellulose esterethers, &c.-Oily or resinous products, which are useful as softening agents for cellulose esters or ethers, are obtained by the prolonged heating of urea, thiourea, or their derivatives, with excess of an alcohol or a ketone or a derivative thereof; a catalyst may be present, and pressure may be employed. Thus, when urea is heated with an alcohol, a urethane is first obtained, and this condenses with an excess of the alcohol. Instead then of starting with the urea, the intermediate reaction product, e.g. the urethane, may take its place. Examples are given of the condensation of (1) urea with benzyl alcohol or 1 : 3 butyleneglycol, using glycerin as the catalyst; (2) urea with ethyl alcohol, acetophenone, or the cyclic acetal obtained by treating glycerin with acetaldehyde; (3) acetylurea with di-acetin; (4) thiourea with 1 : :3-butyleneglycol; (5) urethane with glycerin.

Class 20(3) A door, or window, frame member, for fitting into an opening in a cavity wall structure, comprises a sheet of metal a which is shaped, e.g. by pressing, to channel form and has a width corresponding to the cavity b between the inner and outer portions c, d of the wall, laterally extending feet e being provided at its lower end for imbedding between two courses of the brick-work as the wall is being constructed. If desired, a similar pair of projecting parts e can be provided at the upper end of the member, another lateral projection f, for locating the member, preferably being provided near its lower end. Pairs of ties, consisting of transversely corrugated flexible metal strips g secured, e.g. by welding, to appropriate positions along the sides of the member, are bent over and also imbedded between corresponding courses of bricks during the building of the wall. A flange h is provided on the member for the attachment, e.g. by screws, or nails, of the adjacent vertical side of the door, or window, frame. In a modification the closure member is shaped to form a hollow head of greater width than the cavity, and is adapted for the attachment thereto of a door or window frame, the rear side of the head being formed with at least one flange adapted to enter the cavity b. The closure member is provided with at least the ties g and may have projecting posts such as e.

Title: A method and apparatus for driving holes through unconsolidated earth formations
Inventor: SMITH JOHN T
IPC: E21B7/20
Filed: 1959-07-31
Abstract: 866,658. Boring earth. ROBIN-NODWELL MFG. Ltd. July 31, 1959, No. 26330/59. Class 85. Holes are driven into earth formations by placing a drive point 20 at the end of a drive string 21 which is hammered downwardly. The point 20 is formed with a plain or screwed recess 22 for receiving the drive string 21, and if the hole is to be driven into an unconsolidated formation, e.g. sand or gravel, the point 20 is screwed at 24 to attach a light gauge casing string 25. The drive point 20 may have a winged or other shaped penetrating end. The top of the drive string receives an anvil on which a conventional piledriver operates, and a collar is secured to the drive string to bear on the upper edge of the casing string so that the driving force is partly transferred to the casing string. The string 21 is finally withdrawn, leaving the casing 25 and the point 20 in the hole, but the casing may be retrieved subsequently for use elsewhere. In Fig. 2, the casing 25 is screwed to a guide 26 for the point 20, the blows on the string 21 being transmitted through a collar 28 to the guide 26. The point 20 and string 21 are retrieved, leaving the guide 26 in the ground. If the apparatus is for consolidated ground, the casing 25 is omitted, in which case the abandoned guide 26 may serve as a guide for drilling operations of a different kind in the hole. The point 20 may have a nose piece connected thereto by a shear pin, so that the nose piece may be detached and abandoned if it becomes lodged in the hole. The nose piece projects through the winged lower end of the guide 26. The boring apparatus may be mounted on a lorry, the mast being pivoted to lie horizontally when in transit. The mast is raised to the vertical by an hydraulic cylinder and is pinned in operative position. The pile driver is attached to the mast and means may be provided for rotating the drive string whilst it is subjected to downward impacts or pressure.

Class 87(ii) [Also in Group XIII] Angularly-disposed sections 14 of vulcanized rubber are clamped in a heated vulcanizing mould 1, 3, the ends of the sections being spaced apart in a mould cavity 13, and plastic vulcanizable material is injected under high pressure into the mould cavity to mould a corner piece between and on to the ends, the material 'being subjected to heat and pressure to vulcanize it and unite it to the ends: The resulting unitary article may, as shown, be a tubular refrigerator door gasket. The sections 14 have the cross-sectional shape shown in Fig. 8, and a corner piece of similar shape is moulded with the use of two cores 17, 20. Core 17, Fig. 5, is elbowshaped and has arms 18 which fit within the tubular parts 15 of the strip ends. Core 20 also is elbow-shaped and has a projec- .tion 21 which fits into a recess 22 in the mould to locate the core. Core 20 has a hole 23 through which the material 27 is forced into the cavity by plunger 26 via pasage 24. After vulcanization the mould is opened, core 20 is removed through channel 15<SP>1</SP> and core 17 is removed through a hole 30 in one of the sections 14. In a modified procedure an obtuse-angled mitred cut is formed in strip stock 14, Fig. 7, the stock being not entirely severed, and a corner piece 32 in the form of a triangular gusset is moulded between the mitred edges. The mould parts 1, 2 are clamped together by a cam latch 6, Fig. 2 (not shown).

Abstract: 1435300 Automatic control of speed WEIR PUMPS Ltd 8 June 1973 [8 June 1972] 26724/72 Heading G3R  The speed of a steam turbine 1 is automatically held at a required level by controlling the actuator of a combined stop and throttle valve in accordance with the difference between the actual speed of the turbine and the required speed. Additionally means are provided to close the valve when abnormal conditions are sensed by switching off the electrical supply to the actuator. The speed is measured by an A.C. tachometer 10, 11 and the pulses produced are amplified at 13 and supplied to converter 14. The D.C. output voltage Vs from counter 14 is displayed at 15 and passed to comparator 16 for comparison with reference voltage Vd. The error signal Ve formed is passed through voltage to current converter 18 and supplied to the valve control device 9. The valve controller has a power supply connected at 7 which passes through switch 25. Under overspeed or other abnormal conditions switch 25 is opened which allows the valve to close under spring action to stop turbine 1. The speed signal from 10 is taken additionally to amplifier 21 and to a trigger arrangement comprising filter 22 and relay 23 which when an overspeed occurs causes switch 25 to open. The speed measuring arrangement is connected with relay 23 via line 27 so that failure of 13 or 14 causes switch 25 to open. Other operating parameters, e.g. bearing oil pressure or temperature, could be monitored at 30 or 31 and used to control switch 25. The overspeed arrangement 20 is made  inoperative during starting and a speed limit circuit 34 is used instead. A mechanically actuated overspeed control 32 is provided for use during starting the turbine when the electrical control is inoperative.
